A massive London march organised by far-right activist Tommy Robinson, which drew up to 150,000 participants, descended into violence on Saturday after a small group of his supporters clashed with police who were separating them from a counter-protest, writes Euronews.

At least 25 people were arrested during a march organised by far-right activist Tommy Robinson in London, named ‘Unite the Kingdom’, which drew up to 150,000 people.

The demonstration, which took place on Saturday, quickly turned violent as protesters clashed with police forces as they attempted to separate them from counter-protesters.

London says at least 26 police officers were injured in the scuffles, four of them critically. Police Assistant Commissioner Matt Twist said that officers had policed without “fear or favour”, adding that one officer suffered a concussion, while another suffered broken teeth.

“The arrests are just the start”, said Twist as the London Metropolitan Police vowed to find all those responsible and hold them to account.
